Answer:
Linear because every x, it goes -4 in y. Therefore, it is linear.
Hope this helps :)
Answer
given equation,
x⁵²-21 x+20
A number to be divisible by the another number means that on dividing the remainder should be zero.
if x⁵²-21 x+20 is divisible by x− 1 means that x-1 should completely divide the equation.
so,
x -1 = 0
x = 1
x⁵²-21 x+20 to be divisible it should be equal to zero when x = 1
putting x = 1
= (1)⁵²-21 (1)+20
= 1 - 21 + 20
= 21 -21
= 0
hence x = 1 is the root of the equation
so, x⁵²-21 x+20 is divisible by x− 1.
The zero product property tells us that if we have
xy=0, then we can assume that x and y both equal 0
so
(4k+5)(k+7)=0
we can assume that 4k+5=0 and k+7=0
so
4k+5=0
minus 5 both sides
4k=-5
divide both sides by 4
k=-5/4
k+7=0
minus 7 both sides
k=-7
k=-5/4 or -7
The answer is 32,768. Do the problem same as your example.
Answer:
44.4 units
Step-by-step explanation:
Recall: 2 tangents drawn from an external point from a circle are congruent
Perimeter of the quadrilateral = AB + BC + CD + AD
AB = 3.1 + 8 = 11.1
BC = 3.1 + 8 = 11.1
CD = 11.1 (given)
AD = 8 + 3.1 = 11.1
Perimeter = 11.1 + 11.1 + 11.1 + 11.1
= 44.4 units
